Quantitative evaluation of electroluminescence images of solar cells

physica status solidi (RRL) – Rapid Research Letters, 2010
AbstractA fast converging iterative procedure is proposed to calculate series resistance (Rs) and saturation current (j0) images from two electroluminescence (EL) images taken at two biases. It is not necessary here that for one bias the influence of the series resistance is negligible.

Ageing of DSSC studied by electroluminescence and transmission imaging

Solar Energy Materials and Solar Cells, 2013
Abstract Outdoor stability testing of ionic liquid based dye sensitised solar cells under short circuit (SC) and open circuit (OC) modes has been followed using electroluminescence (EL) and transmission imaging. The study showed a significant influence of the ageing conditions on the stability of the solar cell parameters in the exposure period from ...
